Endophytic bacteria in Coffea arabica L.
Eighty-seven culturable endophytic bacterial isolates in 19 genera were obtained from coffee plants collected in Colombia (n = 67), Hawaii (n = 17), and Mexico (n = 3). Both Gram positive and Gram negative bacteria were isolated, with a greater percentage (68%) being Gram negative. Tissues yielding bacterial endophytes included adult plant leaves, various parts of the berry (e.g., crown, pulp, ...
متن کاملAllometric model for estimating leaf area in clonal varieties of coffee (Coffea canephora)1 Modelo alométrico para estimativa da área foliar de variedades clonais de café (Coffea canephora)
The evaluation of leaf area is required in several agronomic studies given their importance to assess the plant growth. The objective of this study was to use statistical models to estimate leaf area of five clonal varieties of coffee (Coffea canephora) from linear dimensions (length and width maximum). Were used in the studies five varieties of Coffea canephora Pierre ex Froehner: Emcapa 8111,...
متن کاملThidiazuron induced somatic embryogenesis in Coffea arabica L. and Coffea canephora P ex Fr
The rapid direct and repetitive somatic embryogenesis in Coffea arabica and C. canephora genotypes was tested on Murashige and Skoog medium (MS) containing thidiazuron (TDZ) (1-phenyl-3-(1,2,3,-thiadiazol-5-yl)urea) in concentrations of 2.27–11.35s M. Segments taken from cotyledon leaf, first leaf and stalk of regenerated plantlets produced clusters of somatic embryos directly from cut portions...
متن کاملBiosynthesis of chlorogenic acids in growing and ripening fruits of Coffea arabica and Coffea canephora plants.
Chlorogenic acids are major secondary metabolites found in coffee seeds. The accumulation of chlorogenic acids and free quinic acids was studied in Coffea arabica cv. Tall Mokka and Coffea canephora seeds. Growth stages are specified from I to V, corresponding to rapid expansion and pericarp growth (I), endosperm formation (II), mature (green) (III), ripening (pink) (IV), and fully ripened (red...
متن کاملIdentification of novel and conserved microRNAs in Coffea canephora and Coffea arabica
As microRNAs (miRNAs) are important regulators of many biological processes, a series of small RNAomes from plants have been produced in the last decade. However, miRNA data from several groups of plants are still lacking, including some economically important crops. Here microRNAs from Coffea canephora leaves were profiled and 58 unique sequences belonging to 33 families were found, including ...
